ABSTRACT

The present invention discloses an electronic sphygmomanometer calibrating tool, which comprises a platform being coupled to a control system; at least one tool being disposed on the platform for accommodating a testing electronic sphygmomanometer, and the tools being individually coupled to the platform and a pressurizing device through an electric circuit and a gas pipeline; a pulse signal blood pressure simulator being coupled to the gas pipeline, such that when the electronic sphygmomanometer is calibrated, the pressurizing device pressurizes the testing electronic sphygmomanometer by pressurizing the gas pipeline and the control system set the initial state and the maximum pressure for the testing electronic sphygmomanometer. Since the values of the blood pressure from the initial state to the maximum value in increased linearly, therefore the control system can calculate the rest of the values to calibrate the testing electronic sphygmomanometer. Then, the pulse signal blood pressure simulator is turned on to set the pulse blood pressure for the testing electronic sphygmomanometer. Therefore, more than one electronic sphygmomanometer can be set up and calibrated at the same time by the interconnecting structure between the control system and the tools in order to save time and improve the precision of the calibration.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an electronic sphygmomanometercalibrating tool, more particularly to a calibrating tool that makes useof the interconnection between tools to allow manufacturers to calibratetwo or more testing electronic sphygmomanometers at the same time as tosave time and enhance precision.

2. Description of the Related Art

In general, a traditional electronic sphygmomanometer has to go throughthe setup and calibration procedures before it is shipped out of thefactory. The calibration and setup are performed manually; in which acircuit board of the electronic sphygmomanometer, a control system andan air pump are connected, and then the circuit board of the electronicsphygmomanometer is manually set to an initial state, such that air ispumped into the pressure sensor of the circuit board on the testingelectronic sphygmomanometer by the air pump until the air pressurereaches the maximum set value. A variable resistor (VR) is changedmanually to set the maximum set value for the circuit board. However,such method can only calibrate one electronic sphygmomanometer at atime, and also requires a manual operation for the calibration. Suchmethod not only is inefficient, but also wastes a great deal ofmanpower, cost and time.

SUMMARY OF THE INVENTION

In view of the foregoing shortcomings of the prior art, the inventor ofthe present invention focused on the problem to start finding a way forthe improvement and overcome the shortcomings in hope of finding afeasible solution, and conducted extensive researches and experimentsand finally invented the electronic sphygmomanometer calibrating tool inaccordance with the present invention.

Anelectric contact point and an air hole are disposed on each of the toolscorresponding to the testing electronic sphygmomanometer; wherein theair hole is interconnected with the gas pipelines, such that the air inthe gas pipeline will be discharged until its pressure is equal to theatmospheric pressure (which is the initial state) according to theinstruction given by pressing the press button during the test. Thecontrol system will set the testing electronic sphygmomanometer to amaximum pressure, and then compute the value corresponding to eachpressure value by the linear slope relation from the maximum pressurevalue to the initial state. The values obtained are used for calibratingthe testing electronic sphygmomanometer. Therefore, more than oneelectronic sphygmomanometer can be set and calibrated at the same timeby the interconnecting structure between the control system and thetools in order to save time and improve the precision of thecalibration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIG. 1 for an electronic sphygmomanometer calibratingtool according to the present invention. The electronic sphygmomanometercalibrating tool is used to calibrate an electronic sphygmomanometerbefore the electronic sphygmomanometer exits the factory. The electronicsphygmomanometer calibrating tool comprises: a platform 10; at least onepress button 11 being disposed on the platform 10, and three pressbuttons 11 are used in this embodiment, wherein one is for controllingthe air pressure of the initial state, the other one for controlling theair pressure to reach the maximum value, and the last one for enablingthe pulse; a display device 20 being disposed on the platform 10, and acontrol system 30 being electrically coupled with the platform 10 by anelectric circuit.

Further, the platform 10 comprises at least one tool 40 thereon, and thetools 40 are built according to the testing electronic sphygmomanometer,and the tools 40 are connected to the display device 20 and the controlsystem 30 through the electric circuit. The tool 40 also comprises anelectric contact point 41 and an air hole 42 corresponding to eachtesting electronic sphygmomanometer; wherein the air holes 42 areconnected to the gas pipelines 43, and the gas pipelines 43 areinterconnected, and the gas pipeline 43 are extended outward to couplewith a pressurizing device 60. A gas storage tank 61 is disposed on thepressurizing device 60 and coupled to an adjusting valve 62 and an airpump 63 for supplying air. Further, the gas pipeline 43 has an air valve44 on a specific position of the gas pipeline 43.

The gas pipeline 43 is connected to a pulse signal blood pressuresimulator 70, and the pulse signal blood pressure simulator 70 is usedto simulate the pulse signal, and the pulse signal blood pressuresimulator 70 is connected to a press button 11 of the platform 10 by theelectric circuit.

Please refer to FIG. 2. Since the electronic sphygmomanometer 50 iscalibrated according to the present invention before shipping out of thefactory, and the main components of a general electronicsphygmomanometer 50 and the display device 20 are placed on a circuitboard 50, and thus the present invention will focus on the circuit board50 for the calibration. Therefore, when the calibration is performed,the foregoing circuit boards 50 are put into the tools 40 individually,such that the electric contact point 51 and the air hole 52 of thecircuit boards 50 correspond to the electric contact point 41 and theair hole 42 of the tools 40 respectively, such that the circuit boards50 can be connected to the control system 30 and the gas pipeline 43,and operators can press the press button 11 on the platform 10 todischarge the air in the gas pipeline through the air valve 44, and thusthe pressure inside the gas pipeline is maintained at the atmosphericpressure. The control system 30 will set the air pressure state to theinitial state and send the setting to the circuit board 50 of each tool40, and then another press button 11 is pressed, such that the air inthe gas storage tank 61 is distributed and sent to the circuit board 50through the gas pipeline 43 until the display device 20 displays themaximum set value. Similarly, the control system 30 sets that state tothe maximum pressure state and sends the set value of such state to thecircuit board 50 of each tool 40. By the linear proportion relation fromthe maximum pressure value to the initial state (as shown in FIG. 3),the control system 30 will calculate the value for each correspondingpressure value according to the linear proportion relation, and thecalculated results are used for setting and calibrating the testingelectronic sphygmomanometer. The press button 11 of the pulse signalblood pressure simulator 70 is pressed and started to send a specificsimulated pulse pressure value to the circuit board 50 of the tool 40through the gas pipeline 43. The control system calculates and sets theblood pressure relation according to the specified pulse pressure value.Therefore, with the control of the control system 30 and theinterconnection of the tools 40, more than one electronicsphygmomanometer can be set and calibrated at the same time as to savetime and enhance the precision of the calibration.
